MUSIGSIEET.

Specification of Letters Patent.

Patented'sept. 22,1908. I

To all whom iii-may concern: I

Be it known that I, HARRY PIERCE, citizen of'the United States, residing at Kansas City, in the county of VVyandotte' and State, of Kansas, have invented certain new and useful Improvements in Music-Sheets, of which the following is a specification.

This invention has for its object a specially devised perforated music sheetfor pneumaticall y actuated musical instruments, and is especially designed for use with my improved tracker, board and valve system for instruments of this character asset forth in a companion application of even date herewith, Serial No. 391658.

For a full understanding of the invention and the merits thereof and also to acquire a details of construction and the means for eifectin the results, reference is to be had to the fol owing description and accompanying drawings in which igure 1 represents a portion of a music sheetformed in accordance with my invention; and, Fig. 2 illustrates the tracker board v to in the-following in all the views of witldi which the said sheet is intended to be use Corresponding and like parts are referred description and indicated the drawingsby the same reference characters. y

In accordance with my posed to emphasize the a composition by a specially devised pneumatic valve system depending for its operation upon theopening at the same time of any two or more complementary air passages in a tracker board that is formed with two sets of such passages. One set designated l (Fig. 2 is connected to action vacuum chests andthe other set 2 is connected to an additional vacuum chest for a full description of had to my other application, above meninvention it is protioned. The respective passages 1 and 2 e' tend at right angles to each other, as best seen in 2, dinally'elongated and the passages 2-transversely elongated and setback of the respective passages 1 in registry-,with one end thereof.

The sheet, as shown in Fig. l, is formed.

with slots 31 for use with the ordinary passages l and with other and wider slots y for theme or melody of the ordinary double which reference may be r the passages l being longitu-- use in accentuating any particular note or notes. 7

In practical'operation Whenever a slot the size of the slot y passes over the tracker board, it will strike one of the passages 2 as well as the passage 1 just in front of said passage 2, thereby bringing into effect my addi-' tional vacuum chest as well as the ordinary vacuum chests and thereby increasing the suction and accentuating the desired note.

The slots y are for the notes that carry the melody and the slots x are for the notes which are more subdued, for it will be understood that the slots 0; in passing over the tracker bfiard donot register with the passages 2 at a Having thus described the invention, what is claimed as new is:

1. The combination with a music sheet 'having two sets 0 therein, of a tracker 'board having two sets of air passages, the passages of one set being arranged back of corresponding passages in the other set and in transverse alinement With-the ends thereof, each opening of one set of openings in the music sheet being of a length greater than the distance between corresponding passages of both sets whereby to simultaneously open corresponding passages of both sets of passages in the tracker board.

2. The combination with a music sheet formed with two-sets o openings, of a tracker board having two sets ofair passages, one set being longitudinally elongated, and the other set being transversely elongated, and in transverse alinement with .the ends of the longitudinally elongated passages, respectively, one set of the openings in the music sheet being in alinement with the longitudinally elongated passages only, and the other set of openings in the music sheet being in alinement with the other set of passages in the tracker board and of a width to simultaneously uncover only one of such passages, and an end portion of a longitudinally elongated passage.

In testimony whereof I affix in presence of two witnesses.
